DEVELOPMENT OF A GROUND-BREAKING MULTI-JUICE EXTRACTION MACHINE
Abstract
This study centers on the design, development and performance evaluation of a juice extractor developed using
locally-available materials. The machine designed was simple, compact and portable. The size makes it suitable
for household use. The uniqueness of the machine is centered on its ease to assemble and disassemble. The
machine is made up mainly of two units: Power end and Extraction. The power end is where the motor which
transmits power to the shaft is located. The auger shaft which is the main component of the extraction unit
conveys the fruits and squeezes it against the walls of the barrel of the cone shaped end. The motor transmits
enough power to masticate the fruit that is fed in through the hopper and relatively rotates at a slow speed to
achieve proper squeezing. The fresh orange, pineapple and water melon fruits were tested. Result shows that the
average juice yield for orange, pineapple and water melon was 76.5%, 82.0% and 91.9% respectively; juice
extraction efficiencies was 91.9%, 94.5% and 96.7%; and juice extraction losses 6.3%, 6.9% and 4.2% also. The
extractor is powered by a 1hp electric motor. The machine has a capacity to process 0.028m3/hr of oranges,
0.03m3/hr of pineapples and 0.031m3/hr of water melon and cost of machine ₦64,000. Hence, the machine is
affordable and it is recommended for small and medium holder juice processors.
